- the `novel features of construction and operation hereinafter described and particularly pointed out in the claims.

In the accompanying drawings which illustrate a preferred embodiment of the invention,-

Fig. l is an elevational vie-w showing the invention in use;

Fig. 2 is an elevational view of the improved card holder; and

Fig. 3 is a sectional view of a-card holder with a card mounted thereon substantially p on the line 3 3 of Fig. 2.

In using index devices of the so-called visible index type considerable delay is caused by the necessity of permitting all the card holders to return to their original positions after a card has been inspected in order that the indicia upon the exposed margins of the overlapping cards may be inspected in finding another desired card. In v order to overcome this defect I have produced an improved card holder which is partly cut away along one edge to'render a portionl of the card supported. thereby visible from the back when the card holders are swung to the position illustrated in the upper part of Fig. 1.

This improved card holder is illustrated in Figs. 2 and 3 and comprises a back A of sheet material to which is attached, as by a fabric hinge B, a strip C of card-board or fiber having ends projecting beyond back A to be sprung into the channels formed by side flanges D of a visible index holder E. To permit the lower margin of a card which is to be mounted upon the card holder to be seen from the back of the holder, I cut away the lower marginal portion of back A in the manner indicated at F (Figs. l and 2) to provide a longitudinally extending,

.one in the center.

transversely narrow recessin its edge. This Acutting away of the margin is only sufticient toexpose a line o printed matter upon the card, this printed matter to be a duplicate of the indicia that is upon the lowir margin of thev opposite side of the .car f To ermit thev indicia to be. visible from both sldes'of the index holder it is necessary that the card Gsupported by the holder have its lower edge substantially in line with the uncut lower edge of the card holder. I prefer to use for this purpose a sheath II of transparent material' such as celluloid formed by bending a. strip of celluloid upon itself With the rear face slightly wider than the other as shown in Fig. 3 and'with the outer edge rolled as indicated at it to permit easy insertion of the card between the front face of the sheath and back A of the holder. Sheath H may be made fast to the lower portion of the holder in any desiredimanner, the means shown in the drawing comprising three staples I, one at each end and Means for further locking the card in place may comprise diagonal slots J in back A to receive the corners of the card and an integral tongue K formed by further slotting the back A. When a card is inserted with its lower margin in the pocket. formed by the front face of the sheath and back A @and its top sprung under tongue K and its ends in slots J, it is securely .held against displacement inthe proper position.

Fig. 1 illustrates the'lnanner of'using the device. As shown, the card with the name E. F. Allen thereon is being inspected, this card having been exposed by turning back the card holder immediately'thereabove. In this positionthe index indicia of every card in the index holder E is now visible to the user of the index device, the cards below the Allen card by the provision of the overlapping arrangement and the cards above by the provision of the cut-away portion of the holders supporting the same. Hence, if the user desires next to locate the card to Alden,

C. D., it is unnecessary for him to drop the cards above the Allen card before he is able to find the new card inasmuch as he may turn directly to the desired card.

An important feature of the invention consists in ythat the back of the Celluloid Aand a card removably mounted on said sheath overlaps the lower mar 'n of the holder A throughout the Width o 'the holder including the cut-away portion. Thus the sheath is held against transverse flexing by virtue of its engagement with the lower margin and still further by its attachment to the holder at the center where a staple I or other fastener is provided as described. Moreoverv the overlapping relationship of the member A and the front member'of the sheath facilitates the insertion of a card into the sheath inasmuch as the card is guided into the sheath when slipped downwardly along the front surface of' the part A.

By reason of the narrowness of the cutaway vportion of back A of the holder the latter' is not perceptibly weakened and the sheath H may be firmly secured thereto without likelihood of being torn away from the card holder in any ordinary use of the index device.

I claim:

1. A card holder for card index systems having a sheath of transparent material secured thereto at one edge and folded over the body of the holder to form a pocket,

holder with one margin in said pocket, said holder having a portion of the margin covered by said sheath cut away to provide a recess of less width than one wall of the pocket whereby to permit a portion of the, margin of the card to be visible from the back of the holder. l

2. A card holder for index systems having a sheath of transparent material enclosing one margin of the holder to form a pocket, the back f the sheath extending farther from the edge of the holder than the fronty of the sheath and being secured to the holder beyond the edge of said front, a portion of said margin enclosed within the sheath being cut away to leave a longitudinal recess less in width than' one wall of the sheath to display the margin of the 4card. from the back of the holder.

A card holder for u se in index devices of the type having a series of holders swinging into overlapplng relationship with their margins exposed, the holder comprising a sheet back having a portion of its exposed margin cut away to form a transversely narrow recess, and a folded transparent sheath fitting over the exposed margin and overlapping the back at the inner edge of said recess, whereby an index card extending along the front of said back into said sheath is visible along its margin from the back of the holder by virtue of said cutaway portion.

4. A card holder for use in index devices of the type having a series of holders swinging into overlapping relationship with their margins exposed, the holder comprising a sheet back having a portion of its exposed margin cut away, and a folded transparent sheath extending along said margin to form a pocket to receive an index card, the back of said sheath overlapping the uncut portion of said sheet back throughout the length of said cut-away portion.

5. A card holder foruse in index devices of the type having a series of holders swinging into overlapping relationship with their margins expose the holder comprising a sheet back having a portion of its exposed margin out away, and a folded transparent sheath extending along said margin to form a pocket to receive an index card, the back of said sheath overlapping the uncut portion of said sheet back throughout the length of said cut-away ortion, and being secured to the sheet bac intermediate the ends ofthe cut-away portion.
